-To all 'whom 'it may concern:

Be it known that I', Gus'ravr: Atnnn'r LUCAS, ol' G5 liuc Vallier', Levallois-l crret, (Seine.) Republic of France, mechanician, have invented Improvements relating to Sanitary Apparatus, of which the following is a. full, clear, and exact description.

The present invention has for its object an apparatus intended for destroying all fecal matters, and liquid house refuse by automatically effecting their transformation into a colorless, inodorous and inoffensive liquid. I

This apparatus is characterized by. the special arrangement of an anaerobic fermentation chamber divided into a certain number of compartments in each of which the bacteria (anaerobic bacteria) due to the action of fermentation, fix themselves, d'evelop themselves and destroy the organic germs contained in the matter to be treated; these several compartments having each solid and perforated partitions or walls so arranged that a solid partition is always opposite a perforated one; this special arrangement allows the bacteria to attach themselves on the solid partitions and to coming out from this anaerobic fermentation chamber,`

the liquid passes through a purifying chamber in which the nitrification of the nitrogen in the previously dissolved organic matter takes place. The product issuing from this purifying chamber is acolorless inodorous and entirely inoffensive liquid as regards public health.

The present apparatus may be placed in a cesspool already constructed or in a cesspool specially constructed for th is purpose.

The accompanying drawing shows by way of example a mode of practically carrying out the present system of apparatus.

VThe diluted matter to be treated is admitted too the fermentation chamber through the pipe o and enters the compartment bwherc the lirst degree of fermentation takes place; thence, thc matter dividcs into two currents, as shown by the arrows, andsucccssively passes into the lateral chambers c, c, then into the chambcrs d, d, passes intothe central chambers e, c, thcn through the chambers f, f, and finally arrives into the upper chamber g. l

As shown, the perlorations Which cause the several chambers to communicate are so arranged that in each chamber a solid wall or partition is always in front of a perforated one. i

, treated are destroyed by these bacteria.

v ing; niziicri The apparatus being hermetic, the work of fermentation becomcs increasingly cliicacious by reason of the fact that the matter as it docs not find a direct outlet, makes a more prolonged slay in the apparatus; furthermore, the special arrangement of the solid and perforated partitions enables the anaerobic bacteria produced under the action cf iermentation, to al tach themselvcs on the solid partitions and to thus entirely accomplish their work without being carried along or disturbed by the current of liquid circulating through the perforated partitions. During this circulation, the organic substances contained in the matter to be The liquidissuing from this fermentation chamber no longer contains organic matters; this liquid then passes through a filtering vat containing iiltering material and adapted to purify the liquid. In advance of this fermentation chamber is arranged a receiver in which the matter is admitted through the waste pipo and in which it is dil. ln an apparatus for the bacterial 'treatment of fecal matters, liquid house refuse and sewage, u'n'anaerobio fermentation chamber, vertical and horizontal partitions dividing;I the latter into a series of compartments, perforations provided in some of these partitions so that opposite a perforated partition is always arranged a solid one in order to allow the bacteria to attach themselves on these solid partitions, to completely develop themselves and to entirely accomplish their work without beingr disturbed by the liquid current freely circulating through the perforated partitions.

2, ln an apparatus for the bacterial treatment of fecal matters. liquid house refuse and sewage, a receiving chainber, an anaerobic fermentation chamber, verlical and horlzonial walls dividing-the latter into a series oL compartments, perfoi'niions provided in some ot these partitions so that opposite :t perforated partition is-always arranged a solid one, a connnunication between the lower part of the anaerobic fermentation chamber and the lower part of the receiving' chamber, u. puriiyingchamber containing filterand communicating at its upper part with the upper part of the anaerobic fermentation chamber.

The foregoing speciiication o my improvements relating to sanitary apparatus signed by me this eleventh day of December, 1905. i
